Environmental Limitations
100
No longer living in a particular region but still exists somewhere else vs no longer living anywhere on the planet.
What is extirpation vs extinction?
100
Animal that hunts and kills its prey, usually found at the top of the food chain
What is a predator? (it is predaceous)
100
Feeds on both meat and vegetation
What is an omnivore?
100
Swamp-a seasonally flooded bottomland with more woody plants than a marsh and better drainage than a bog.
What is the most biologically productive habitat type?
100
Population numbers are limited due to predator-prey dynamic and food and habitat availability vs population numbers being limited due to anthropological values such as flooding, hunting, crop damage, etc.
What is biological carrying capacity vs cultural carrying capacity?
200
Facing imminent extinction vs likely to become endangered if limiting factors are not reversed
What is endangered vs threatened?
200
Grass (uses photosynthesis to convert light energy to organic matter)
What is a primary producer?
200
Feeds on fruit
What is a frugivore?
200
Federal Policy on Wetland Conservation, fencing, managing recreational activities, public support
What are methods of protecting wetlands?
200
Food, shelter, water, space, birth rates, survivorship
What are factors that limit biological carrying capacity?
300
Sensitive to activities which may make it endangered or threatened
What is vulnerable or species of special concern?
300
Primary consumer
What is a herbivore?
300
Feeds on seeds
What is granivore?
300
Marshes (tidal and non-tidal), swamps, bogs, and fens
What are examples of wetlands?
300
transition of temporary plant communities that one after the other eventually lad to one community that is more permanent
What is succession?
400
Species at Risk Act, Nova Scotia Endangered Species Act, and recovery teams
How are species protected?
400
Revealing relationships between predator and prey vs revealing all interconnected relationships between organisms
What is a food chain vs a food web?
400
Supplements diet by feeding on feces
What is coprophagy?
400
Water recharge, natural shoreline protection (from wave and wind erosion), important source of oxygen, habitats, area for endangered species, storage base for carbon, nutrient source, source of diversity, natural filter and sink of pollutants, spawning and nursing areas, economic benefits, bird watching, prevention of floods (sponges)
Why are wetlands beneficial?
400
Eroded soil from an agricultural field that enters a river, pesticides from lawns and gardens from a town that enters a river after a rain event, oil gas and antifreeze carried into rainwater into a river
What is non point source pollution? (Point source pollution examples would be: a discharge from a waste water treatment plant pipe that enters the river, an industry that empties effluent into a river)
500
American Marten and Eastern Moose vs Barrow's Goldeneye and Wood Turtle
What are two endangered vs two vulnerable species?
500
Mimicry, camouflage, chemical defense, group behavior, physical adaptations
What are methods some animals use to avoid being captured?
500
Feeding on an assortment of food vs feeding on one type of food
What is generalist vs specialist?
500
65% of Atlantic Coastal Salt Marshes are gone
What is a wetland that has experienced massive depletion?
500
local genetic variation, public opinion, cost, local adaptation
What are factors a wildlife manager must consider before carrying out a species re-introduction?
